Two contracts worth a total of about $4.75 billion have been awarded for the building of the substructure and airside infrastructure at Changi Airport Terminal 5 ahead of the start of construction later in May.
The airport’s operator said on May 5 that the substructure includes the foundation and basements of the main passenger terminal.
Changi Airport Group (CAG) said the substructure contract, valued at about $3.8 billion, was awarded to a joint venture between the Singapore branch of China Communications Construction Company (CCCC) and Obayashi Singapore, a subsidiary of Obayashi Corporation, one of Japan’s biggest general contractors.
The joint venture will be responsible for building the foundation and basements of the main passenger terminal and ground transport centre, and a portion of the tunnels linking T5 and the existing Terminal 2.
Covering about 140ha with a basement depth of up to 28m, the substructure site is equivalent to about 5,200 Olympic-size swimming pools.
CCCC – the world’s largest construction company for large-scale infrastructure – previously developed two aircraft taxiways connecting Changi Airport’s runways 2 and 3. It also developed two underground tunnel sections for vehicles beneath the taxiways.
Meanwhile, Obayashi Singapore was involved in the construction of the Changi Airport control tower and Jewel Changi Airport, a shopping complex at the airport.
A separate contract valued at $950 million was awarded to Hwa Seng Builder, a civil engineering company, for airside infrastructure works at T5. The airside is the part of the airport beyond passport control and Customs.
These works include the development of remote aircraft stands, connecting taxilanes and ancillary support buildings, such as substations and an airfield lighting control centre.
Taxilanes are short stretches of roadways that connect the main taxiways to aircraft parking areas.
The Singapore-based Hwa Seng Builder has been involved in various aviation projects in Singapore, including at Changi and Seletar airports, said CAG.
Mr Ong Chee Chiau, CAG’s managing director for Changi East, said CCCC and Obayashi Singapore have a wealth of experience in civil engineering, construction and project management.
Hwa Seng Builder, meanwhile, has valuable local expertise and a deep familiarity with Changi Airport, added Mr Ong.
“The appointments of the contractors for substructure construction and airfield works bring us closer to the start of T5’s construction,” he added.
T5 is part of the new Changi East development that includes Changi Airport’s third runway, as well as cargo complexes and other supporting aviation and ground transport infrastructure, such as engineering support facilities. This is Changi Airport’s largest expansion project to date.
When operational in the mid-2030s, T5 can handle about 50 million passengers a year, on top of Changi Airport’s current capacity of 90 million.
Prime Minister Lawrence Wong said in his May Day Rally speech on May 1 that construction on T5 will start in “two weeks’ time”.
